The SD fuel pumps. Surely there a few around still running them. I must have made 4 or 5 hundered of them (Ex witch has the quick books). They were the first to market for the Dmaxes that I remember (before Prepator and the off shoot FASS). It's not like I was a big outfit or nothin. Ever seen SD sleeves, SD Centerlink, SD manifolds, SD nitrous systems, SD Chiller (W/M injection). SD pressure block. SD moded CP3s, SD moded regulators, so on and so forth (most was 1st to market for the Dmax I'm proud to say, but sad to say it was demolished by an angry EX). SoCal is making the sleeves and manifolds now :hug: (many vendors sells them). I've got more in store though.
